UNooUrLnve DEVICE.

Toall whom it may concern: I

Be known that-wefLoUis G. MILLER and Fnnnnm'on C. DANKMYRR, both citizens of the United States, and both residing in the borough of' Westmont; in the county of Gambria'and State of Pennsylvania, have invented certain new and useful Improvements in Uncoupling Devices; and we do hereby declare the following to be a full,

clear, and exact description of the inven* tion, such-as will enable others skilled in the art to which itappertains tOiTlil-k and use the same. r s

Our invention relates to uncoupling devices also known as coupler release riggingg for use on freight cars, whereby the coupler can be released or'engaged Without the necessity 'for the brakeman or switchman going between the cars, thereby conducing to sa ety. Our apparatus is of simple construction, readily installedor dis-assembled without cutting out or replacing rivets, screwing the nuts of bolts, or taking off or putting many auxiliary appurtenances. a

We will now, in order to make the matter more clear, refer to the accompanying sheet of drawings in which like characters of ref erence indicate like parts.

i so Figure 1 is a front elevation of the uncoupling device and a portion of the end of the car;

- Fig. 2 is a top plan view oi thedevice drawn on a larger scale, the end wallof the.

, drical opening 5therein and a slot 6 in the upper portion thereof. 7 is an uncoupling rod which is provided with a cylindrical enlargement or journal bearing 8, which either may be formed integral therewith or by -1neans of an annular sleeve mounted thereon, of size adapted to fit within tliecylin- .drical opening in the journal bearings. 9

is the operating arm of the uncoupling rod which is bent at an angle 'to the body of the rod and. also has an offset to allow it to clear the end sill. 10 is the crank arm formed by bending the other end of the rod, and provided with a link ll mounted thereon, which linlr is secured in place by 7 the bent ends of the crank arm and con nected with the locking pin 12 by rneansof aneye end, as illustrated. Referring to Fig. 6, the enlargement on the uncoupling rod 7 is forinedvintegral therewith, and as illustrated in Fig. 7, this enlargement is made by riveting the annular sleeve 13 thereto by means of the ri et 1%, the red with the sleeve mounted thereon being 15.

trated, the upward movement of the open atlng arm 9 will lift the loclring'pin from the coupler and allow it to be bpened in due 36 course of operations and when the couplers are together, the o )erating arm 9 is turned or dropsdownwardly, thereby allowing the locking pin to drop into When the parts are in lines on the rawings, the bent ends ofithe uncoupling rod 7, namely, the operating arm 9 and the crank arm 10, serve to retain.

The uncoupling rod may have other projections adjacent the journal boxes to retain itin normalpposition. The parts be ing in position shown by the full lines in Fig. 1, when it is desired to remove the 0011 'pler release rigging, the operating arm. 9 is turned upwardly .until it is substantially horizontal and beyond its usual upper posiarm 10 is inaline with the slot 6 of the right-hand -journal =bearing land the entire rod can thenbe slid 'to the left, thereby withdrawing the enlargements "B or the sleeve 13 from 5 sition, as s own by'the full no i semble or dis-assemble the apparatus.

Although we have shown and described our improvements in considerable detail, we do not wish to be limited to the exact and spe eifie details shown and described, but may use such substitutii'nis, modifications .or

u uivalents thereof, are embraced within the scope of our invention, or as pointed out in the claims.

Having thus described our invention, What we claim and desire to secure by Let ters Patent I--- it In a eoupler release rigging. an UHCULI- pling rod pi'i'ii'ided with a pair of cylin drical enlargements ins-untt-d in journal boxes, provided with slots in their upper.

surfaces smaller than said enlargements and larger than the body of the rod.

2. In a coupler release rigging, an uncoupling rod provided with a pair of cylindrica] enlargements mounted in journal boxes, provided with slots in their upper surfaces smaller than said enlargements and larger that the body: of the rod, said rod smaller than said enlarged, journals and larger than the body of the rod, the ends of said coupling rod being bent and adaptedto normally retain. said rod in operative position within its bearings. v

4. In a coupler release rigging, an uncoupling rod provided with a plurality of enlarged journals mounted in journal boxes, provided with )iLS in their upper surfaces smaller than said enlarged. journals and larger than the body of the rod, stops on said rod adjacent to the journal boxes adapted to manually retain it in operative position within its bearings,

In testimony whereof we hereto aliix our signatures.
